I have a project coming up that requires me to sync up with the MLS (multiple listing service) that realtor's use. I'm looking for a PHP class that does all the syncing for me all ready. I have done Google searches for various phrases, but all that comes up is canned software packs which im not interested in. Thanks for the suggestions.
I don't know how successful you will be in finding an 'all in one'. As far as I know (and admittedly, it was a couple of years ago that I was looking into this), each location has its own MLS 'service', and not necessarily anything in common other than the name... that is to say, across any two locations there is not necessarily a single "you access the data this way".
